I'm confused about one thing. All news outlet are reporting this as "occupation of Crimea" as if Crimea was not politically a part of Ukraine proper, as if Russian army in Crimea is not the same as Russian army in the Ukraine even though Crimea is part of the Ukraine. Why is that? Is it because the majority of Crimea's population is ethnically Russian? Or is Crimea a disputed territory, like Abkhazia?
